Examples
Copy
// Set default precision to 64 bits.
gmp_lib.mpf_set_default_prec(64U);

// Create, initialize, and set a new floating-point number x to 100.
mpf_t x = new mpf_t();
gmp_lib.mpf_init_set_si(x, 100);

// Create and initialize a new floating-point number z.
mpf_t z = new mpf_t();
gmp_lib.mpf_init(z);

// Set z = x * 2^8.
gmp_lib.mpf_mul_2exp(z, x, 8U);

// Assert that the value of z is 25600.

// Release unmanaged memory allocated for x and z.
